Yesterday's post on Surra de Bunda, a Brazilian dance move in which a female rapidly buffets a man's face with her rear, brought a wealth of new information. Chiefly: Surra de Bunda does not mean "ass licking" but "butt fighting."

The lyrics are sung by a stripper, and are addressed to a guy watching the show, and she's contemptuous of him. She calls him "safado," (presumptuously raunchy) and she says, disdainfully, that he's thinking this is all real easy, watching her butt. Well, now that he's blotto ("chapado") on tequila, the stripper is going to take her revenge. She's going to spank him with her butt. ("Bate com a bunda, bate, bate…")
